Overview

This ENU-induced point mutation in non-coding sequence provides a strong model for late-infantile neuronal ceroid lipofuscinosis without the caveats associated with neomycin phosphotransferase.

Detailed Description

Homozyogtes can be phenotypically identified by a tremor and hunched posture by 3.5 to 4 months of age. The tremor is intermittent and more pronounced when walking. The tremor, ataxia, and diminished locomotion progress and homozygotes die by 6 months of age. Myelin figures in the white matter, and eosinophilic and luxol fast blue positive neuronal inclusions are found, but retinal degeneration and diminished electroretinogram readings are not found. The molecular defect is a T to C point mutation in a splice donor site just downstream of exon 8. While this is a good model for late-infantile neuronal ceroid lipofuscinosis, the lack of an ocular phenotype differs from the disease in human.

Development

The Tpp1^m1J mutation was identified in the progeny of an ENU treated C57BL/6J, which was part of a region-specific mutagenesis screen in the laboratory of Dr. Simon John. The mutagenized C57BL/6J male was bred to C3Fe.Cg-Rw heterozygous females, and a male F1 offspring that was heterozygous for Rw and any ENU-induced mutations was bred to a C3Fe.Cg-Hm +/+ Rw female. One of their female offspring heterozygous for Rw and any inherited ENU-induced mutations was backcrossed to its F1 father (also heterozygous for Rw and any ENU-induced mutations). The recessive Tpp1^m1J mutation was identified in their progeny and this mutant was used to propagate a line that was sibling inbred to homozygosity. At F18 this line was outcrossed once to C57BL/6J and then again intercrossed to homozygosity, reaching generation F18N1F12 in 2013. Thus, this STOCK background consists predominantly of C57BL/6J and C3HeB/FeJ with possible trace contributions from C3H/HeH, 101/H and other undefined backgrounds.

Mammalian Phenotype Terms by Genotype

The following phenotype relates to a compound genotype created using this strain

Genotype: Tpp1^m1J/Tpp1^m1J
STOCK Tpp1/GrsrJ

behavior/neurological phenotype

hunched posture
- evident by 3.5 to 4 months of age

tremors
- evident by 3.5 to 4 months of age, tremor initially appears intermittent and more pronounced when walking then becomes constant as overall symptoms worsen with age

mortality/aging

premature death
- all homozygotes die by 6 months of age

muscle phenotype

myopathy
- histology at 6 weeks of age reveals a few inflammed and degenerating muscle fibers, and at 19 weeks of age there are inclusions in muscle, small muscle fibers and rowing of nuclei in muscle fibers

nervous system phenotype

neuronal cytoplasmic inclusions
- by 17 weeks of age there are eosinophilic and luxol fast blue positive cytoplasmic inclusions in motor neurons in spinal cord and other large neurons in the brain
- by 19 weeks of age there are also myelin figures in the white matter and inclusions in muscle and bone marrow macrophages

We will fulfill your order by providing at least two carriers for each strain ordered. The total number, sex, and genotypes provided will vary, although typically 8 or more animals are provided. Please check genotypes which will be recovered. While the genotypes of all animals produced will be communicated to you prior to scheduling shipment, the genotypes of animals provided may not reflect the mating scheme and genotypes described in the strain description. Animals are typically ready to ship in 11-14 weeks. If a second recovery is required to produce the minimum number of animals, then delivery time would increase to approximately 25 weeks. If we fail to produce animals of the correct genotype, you will not be charged. We cannot guarantee the reproductive success of mice shipped to your facility. If the mice are lost after the first three days (post-arrival) or do not produce progeny at your facility, a new order and fee will be necessary.

Cryorecovery to establish a Dedicated Supply for greater quantities of mice. Mice recovered can be used to establish a dedicated colony to contractually supply you mice according to your requirements. Price by quotation.

Payment Terms and Conditions

Terms are granted by individual review and stated on the customer invoice(s) and account statement. These transactions are payable in U.S. currency within the granted terms. Payment for services, products, shipping containers, and shipping costs that are rendered are expected within the payment terms indicated on the invoice or stated by contract. Invoices and account balances in arrears of stated terms may result in The Jackson Laboratory pursuing collection activities including but not limited to outside agencies and court filings.

The Jackson Laboratory's Genotype Promise

The Jackson Laboratory has rigorous genetic quality control and mutant gene genotyping programs to ensure the genetic background of JAX® Mice strains as well as the genotypes of strains with identified molecular mutations. JAX® Mice strains are only made available to researchers after meeting our standards. However, the phenotype of each strain may not be fully characterized and/or captured in the strain data sheets. Therefore, we cannot guarantee a strain's phenotype will meet all expectations. To ensure that JAX® Mice will meet the needs of individual research projects or when requesting a strain that is new to your research, we suggest ordering and performing tests on a small number of mice to determine suitability for your particular project.
